Abstract
An assembly for reversing a fluid driven motor. The assembly includes a fluid driven motor, and a reversing valve that reverses inlet and exhaust porting to and from the fluid driven motor. An actuation device opens an actuation valve and a fluid supply valve. The actuation valve causes the reversing valve to reverse the inlet and exhaust porting to and from the fluid driven motor when the actuation device opens the actuation valve. The fluid supply valve allows fluid to flow through the fluid supply valve to the motor when the actuation device opens the fluid supply valve. The fluid supply valve also prevents fluid flow through the fluid supply valve to the fluid driven motor when the fluid supply valve is closed.
